Re: water pressure guage problem

etdugas, you did not mention if you did in fact have a good stream coming out of the pisser. If you do then you just have a blockage somewhere in the tubing. Were you running shallow just before this problem, you could have picked up some grass, shell, ect. I always carry a can of compressed air in my boat and blow out the tube that goes up to the guage, the pee-hole itself, and the tube going into the block. If you have an air-compressor at the house/shop try that then run it on the hose, and if you get 5lbs on the hose then you will probably get alot more in the water. If that does not work you may want to check/replace the water pump, or do an acid flush, neither one of these is hard. post back, hoped i helped.
